Sape is the collective designation given to the world's various bipedal species, comprising five classes: Mammal, Bird, Reptile, Amphibian, and Fish. Sapes are physically characterized by their bodily orientation of two arms terminating in hands, and two legs terminating in feet. Sapes are capable of speech, written language, complex thought, diverse social activity, and elaborate architecture, as compared to their non-sape counterparts.

The creation of sapes is assumed to have been the final act of the Dreadwyrm civilizations in the aftermath of the Void War.
